Detailed explanation-1: -Key. 1. What are fossils? Answer: Fossils are the remains of things that lived a long, long time ago.
Detailed explanation-2: -The most common method of fossilization is permineralization. After a bone, wood fragment, or shell is buried in sediment, it may be exposed to mineral-rich water that moves through the sediment. This water will deposit minerals, typically silica, into empty spaces, producing a fossil.
Detailed explanation-3: -What conditions favor the formation of fossils? How might this cause the fossil record to be biased? The organism generally must have hard parts such as shell, bone, teeth, or wood tissue; the remains must escape destruction after death; and the remains must be buried rapidly to stop decomposition.
Detailed explanation-4: -Coat outside of object with layer of petroleum jelly. Press the object into the clay to make a model. Remove object carefully from clay. Place the clay with the object’s shape into the plastic bowl. Slowly pour/drizzle white glue into the imprint. More items •09-Aug-2019
